• THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R410A), WHICH DOES NOT DESTROY THE OZONE LAYER. R410A refrigerant is apt to be affected by impurities such as water, oxidizing membranes, and oils because the pressure of R410A refrigerant is approx. 1.6 times of refrigerant R22. As well as the adoption of this new refrigerant, refrigerating machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating machine oil does not enter the refrigeration cycle of a new-refrigerant air conditioner. To avoid mixing refrigerant and refrigerating machine oil, the sizes of charging port connecting sections on the main unit are different from those for the conventional refrigerant, and different size tools are also required. For connecting pipes, use new and clean piping materials with high- pressure withstand capabilities, designed for R410A only, and ensure that water or dust does not enter. Moreover, do not use any existing piping as its pressure withstand may be insufficient and may contain impurities.New refrigerant air conditioner installation CAUTION This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a contact separation of at least 3 mm in all poles. The installation fuse (25A) must be used for the power supply line of this air conditioner. To disconnect the appliance from the main power supply DANGER

• Never modify this unit by removing any of the safety guards or bypassing any of the safety interlock switches.
• Do not install in a place which cannot bear the weight of the unit.Personal injury and property damage can result if the unit falls.• Before doing the electrical work, attach an approved plug to the power supply cord.Also, make sure the equipment is properly earthed.• Appliance shall be installed in accordance with national wiring regulations.If you detect any damage, do not install the unit. Contact your Carrier dealer immediately. CAUTION

• Exposure of unit to water or other moisture before installation could result in electric shock. Do not store it in a wet basement or expose to rain or water.• After unpacking the unit, examine it carefully for possible damage.
• Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify the noise level of the unit or where noise and discharged air might disturb neighbors.• To avoid personal injury, be careful when handling parts with sharp edges.
• Please read this installation manual carefully before installing the unit. It contains further important instructions for proper installation. REQUIREMENT OF REPORT TO THE LOCAL POWER SUPPLIER Please make absolutely sure that the installation of this appliance is reported to the local power supplier before installation. If you experience any problems or if the installation is not accepted by the supplier, the service agency will take adequate countermeasures.Remark per EMC Directive 89/336/EEC To prevent flicker impressions during the start of the compressor (technical process), following installation conditions does apply. 1. The power connection for the air conditioner has to be done at the main power distribution. This distribution has to be of an impedance. Normally, the required impedance is reached at a 32A fusing point. Air conditioner fuse has to be 16A max.!2. No other equipment should be connected to this power line. 3. For detailed installation acceptance, please contact your power supplier whether its restriction does apply for products like washing machines, air conditioners or electric ovens.4. For power details of the air conditioner, refer to the rating plate of the product. GB - 1Installation Place

• Tightening torque of flare pipe connections The operating pressure of R410A is higher than that of R22 (approx. 1.6 times). It is therefore necessary to firmly tighten the flare pipe connecting sections (which connect the indoor and outdoor units) up to the specified tightening torque. Incorrect connections may cause not only a gas leakage, but also damage to the refrigeration cycle.

• Open the valve stem all the way out, but do not try to open it beyondthe stopper.• Securely tighten the valve stem cap with torque in the following table: Wiring Connection 1. Remove the valve cover from the outdoor unit.2. Connect the connecting cable to the terminals as identified with theirrespective matched numbers on the terminal block of indoor andoutdoor unit.3. When connecting the connecting cable to the outdoor unit terminals,make a loop as shown in the installation diagram of indoor andoutdoor unit to prevent water coming in the outdoor unit.4. Insulate the unused cords (conductors) from any water coming in theoutdoor unit. Proceed them so that they do not touch any electrical ormetal parts. Stripping length of the connecting cable CAUTION
• Wrong wiring connection may cause some electrical parts burn out.• Be sure to comply with local cords on running the wire from indoorunit to outdoor unit (size of wire and wiring method, etc.).• Every wire must be connected firmly.• This installation fuse (25A) must be used for the power supply lineof this air conditioner.• If incorrect or incomplete wiring is carried out, it will cause anignition or smoke.• Prepare the power supply for exclusive use with the air conditioner.• This product can be connected to the mains.Connection to fixed wiring: A switch which disconnects all polesand has a contact separation of at least 3 mm must beincorporated in the fixed wiring.

When two indoor units are installed in the separated rooms, it is not necessary to change the selector switches. Remote control selector switch

• When two indoor units are installed in the same room or adjacent two rooms, if operating a unit, two units may receive the remote control signal simultaneously and operate. In this case, the operation can be preserved by setting either one indoor unit or remote control to B setting. (Both are set to A setting in factory shipment.)

• The remote control signal is not received when the settings of indoor unit and remote control are different.

• There is no relation between A setting/B setting and A room/B room when connecting the piping and cables. Setting of Remote Control Selector Switch
